Repair of Spinal Cord Injury by Co-Transplantation of embryonic Stem Cell-Derived Motor Neuron and Olfactory Ensheathing Cell
Background: The failure of regeneration after spinal cord injury (SCI) has been attributed to axonal demyelination and neuronal death. Cellular replacement and white matter regeneration are both necessary for SCI repair. In this study, we evaluated the co-transplantation of olfactory ensheathing cells (OEC) and embryonic stem (ES) cell-derived motor neurons (ESMN) on contused SCI. Methods: OEC...
متن کاملNoninvasive bioluminescence imaging of olfactory ensheathing glia and schwann cells following transplantation into the lesioned rat spinal cord.
In this study, we assess the feasibility of bioluminescence imaging to monitor the survival of Schwann cells (SCs) and olfactory ensheathing glia cells (OECs) after implantation in the lesioned spinal cord of adult rats. To this end, purified SCs and OECs were genetically modified with lentiviral vectors encoding luciferase-2 and GFP and implanted in the lesioned dorsal column. The bioluminesc...
متن کاملOlfactory ensheathing cells and spinal cord repair.
The olfactory ensheathing cell is a specialized glial cell that assists in growth of the axons of the olfactory sensory neurons as they are generated and regenerated throughout adult life. There is increasing evidence in animal models that transplantation of olfactory ensheathing cell promotes recovery after transplantation into the injured spinal cord. Olfactory ensheathing cell transplants ha...
متن کاملAnimal experiments and clinical application of olfactory ensheathing cell transplantation for treatment of spinal cord injury★
BACKGROUND: The olfactory epithelium can still generate new neurons after arresting its growth and development in the human body. Axons can still be generated and pass through peripheral tissue to reach the olfactory bulb. Thus, olfactory cells have been widely used in the repair of spinal cord injury. OBJECTIVE: Using animal experiments in conjunction with a clinical study of olfactory ensheat...
متن کاملTransplantation of autologous olfactory ensheathing cells in complete human spinal cord injury.
Numerous studies in animals have shown the unique property of olfactory ensheathing cells to stimulate regeneration of lesioned axons in the spinal cord. In a Phase I clinical trial, we assessed the safety and feasibility of transplantation of autologous mucosal olfactory ensheathing cells and olfactory nerve fibroblasts in patients with complete spinal cord injury. Six patients with chronic th...
